Improved nursing-bottle



M. KNAPP, or RACINE, Wisconsin.

.Leners Patent No. 86,762, dated Fama/ry 9, 1869.

'IMPRovED Nnnsmsormnn.

The Schedule referred 'to in these Lettera Patent and making part of thesame.

To all whom it may concern:

Be it` known that I, AIM. KNAPP, of Racine, in the county of Racine, inthe State of Wisconsin, have invented a newl and useful Improvement inNursing- Bottles; and I do hereby declare that the following is a fulland exact description .thereof,'reference being had to the accompanyingdrawings, and to the letters of reference marked thereon, making a partof this specification, in which- Figure l is van elevation of myinvention, arranged for use.

Figure 2, a sectional elevation of the cap, showing the position of thevalves. 1

Figure 3, an enlarged view of the air-valve, which regulates thepressure of atmosphere on the milk.

The nature of my invention consists in the use of a check-valve, forholding the milk in a. flexible pipe and also in the use' of auair-valve, for regulating the atmospheric pressure opon the surface ofthe milk inside of the bottle; and, further, in graduating the bottlewith suc-h marks as will indicate the amount of milk in the bottle', andalso the quantity drawn out by the child.

In order to give a correct understanding of my invention, I have markedcorresponding parts with similar letters, and will now give a detaileddescription.

v A represents a common nursing-bottle, which should be made of glass,in order that the graduating-marks,

. 2 oz.,,- 4 02., 6 oz., Sac., may be either blown in the glass, ormarked on the outside, as seen at tig. 1, for the purpose of indicatingthe amount of milk iu the bottle, and that which is drawnout.

This graduating-arrangement I considerimportant,

for if it, or a similar device, is not used, the quantity of milk mustnecessarily be measured before it is put in the bottle, or the childmust take au indefinite quan'- tity, which is frequently dcleteroustothe child, espe.

cially when in the care of an inexperienced nurse.

A cap, or cover, B, is made of suitable metal, and lined on the insidewith cork, D I), in order that it may be iitted closely around thebottle A, and prevent the escape-of milk, or the ingress of air, andalso be prevented from getting loose by ordinary use.l I

This cap B has .a screw-valve, E, with an opening,

' f, through it, and arranged Vto prevent the air from entering thebottle A, and to regulate the quantity which is necessary to force milkthrough the tube O C, when the latter is'drawn Vupon by the child.

This cap' B has also a tube made fast to it by a screw-thread, as seenat 11a-iig. 2, for supporting an outer rubber pipe, O C, and an innerrubber pipe, H,` and a glass tube, H', the pipes and tubes beinglusedfor conveying theinilk from the bottle A.

The tube m is`also arranged fth-a check; I', which is used to keep, thetube G C full of milk, at such times as the child is to draw it from thebottle A This check-valve I, I consider importantior keeping the pipe 0C full, and obviating the distressing results arising from the childsdrawing air into thestomach before it receives milk.

The: pipe Hand the pipe C G have been used before, and are therefore notconsidered new, but are used in connection with the valves, in order tomake the device complete.

Cpe/ration.

The cap B can be removed from -bottle A, so as to lill the bottle withmilk, after which the .cap can b replaced, and the bottle is ready foruse.

Having thus described my invention, I do not claim to have originatedgraduated bottles, as they have been used before, but not asnursing-bottles; neither doI claim separately the pipe O and valves E I,as the former has been used in connection withmursing-bottles, and thetwo latter, for holding iiuidin exible pipes; but 'f f What I doclaim,anddesire to secure'by Letters` Patent, is-

As a new article ci' manufacture, in combination with the bottle A, thearrangement of the pipe O and valves fl? I, in the manner described, andfor the purpose set orth.
